Hello Statalist community.
I am currently trying to do a propensity score matching with the psmatch2 package. I have a treatment variable (regulated firm --> 'regualted') and want to find a statistical twin in a large dataset according to asset size (--> logfixedassets). However, this firm must be in the same sector/industry (i.nace2) and from the same country (i.ctrycode). If I run this code, however, I get matches that do not fulfill the sector and country requirements:
psmatch2 regulated logfixedassets i.nace2 i.ctrycode, n(3)
Can anybody help me?
Thank you
Lennart
